Clearances are measured from the hearth surface, door opening,
or centerline as noted in fig. 3 and 4.
Add two inches to mantel and top trim clearance when Riser
Bar is installed.
A: Hearth Protection, width from centerline: 17 1/4” (438 mm)
B: Hearth Protection, forward from door opening:
16” (406 mm)
C: To Side Trim, 1” max. thickness, from centerline
19 1/2” (495 mm)

To Mantel, 11 1/2” max. depth: 54” (1372 mm)
Hearth Protection Requirements
The floor area in front of fireplace insert must be protected from
live sparks and radiant heat. See Fig. 3.
• Materials:
Hearth protection must be non combustible
insulating board, or the equivalent mortared masonry
material. Alternate protection must composed of
materials as specified by NFPA 211.
• Protected Area:
16” Deep x 34 1/2” Wide, for both the
U.S. and Canada. Fig. 3.
A) Front - The protection must extend at least 16 inches
(406 mm) forward from the fireplace insert door opening.
B) Sides - Protection must extend 17 1/4 inches (438
mm) to both sides of the centerline of the insert.
• Flush Hearth:
Where the hearth construction is flush with combustible
floor materials, the insert must be elevated with use of the
2” Riser Bar supplied.
• Raised Hearth:
Where the hearth construction is a minimum of 2 1/2” thick,
the insert may be installed without use of the Riser Bar.
Mantel Clearance Detail - measured from the
hearth surface to the lowest mantel surface.
Insert Riser Bar is not installed.
Add two inches to each clearance dimension when
Insert Riser Bar is used.
Clearance Requirements
The following clearances and hearth specifications are the
minimum requirements for installing this appliance into a
solid fuel-burning fireplace. See Fig. 3.
A combustible surface is anything that can burn (i.e.
sheet rock, wallpaper, wood, fabrics, etc.). These surfaces
are not limited to those that are visible and also include
materials that are behind non-combustibles.
If you are not sure of the combustible nature of a
material, consult your local fire officials. “Fire Resistant”
materials are considered combustible; they are difficult
to ignite, but will burn. “Fire-rated” sheet rock is also
considered combustible.
Always maintain the proper clearances to allow for
the flow of ventilation air around the insert.
